The last unbeaten has fallen. The last winless team is winless no more.

Welcome to “Upset Sunday” in the NFL.

With all the hype surrounding the Patriots/Broncos epic matchup in Denver, the first big headline of the day came from Arrowhead Stadium. The Kansas City Chiefs, who fired head coach Todd Haley less than a week ago, pulled off the shocker of the year: a 19-14 victory over the previously undefeated Packers.

Kyle Orton threw for 299 yards – 64 more than Aaron Rodgers. Jackie Battlescored Kansas City’s lone touchdown of the game to seal the deal. Rodgers pulled Green Bay to within five in the closing minutes, but the Chiefs were able to run out the clock. The end result: the Packers’ first loss since Dec. 19, 2010, and a Gatorade bath for interim Chiefs head coach Romeo Crennel.

The Packers still have the inside track to the No. 1 seed in the NFC, but Sunday’s result gives other teams hope.

Meanwhile, at Lucas Oil Stadium, another long streak ended. The Indianapolis Colts finally won a game. With a 27-13 victory over the Titans, Indianapolis avoided becoming the second 0-16 team in NFL history, (Detroit is alone in that regard). The Colts’ defense forced three turnovers, and Donald Brown rushed for 161 yards, including an 80-yard touchdown in the fourth quarter that sealed the deal.
